This paper presents a novel wearable interface for the foot: a shoe-integrated tactile display that enables users to obtain information through the sense of touch via their feet. A 16-point array of actuators stimulates the sole of the foot by inducing different vibration frequencies. A series of experiments were conducted with 20 sighted and 5 blind voluntary subjects to evaluate the role of tactile perception by the human foot and the tactile sensitivity of the plantar surface. Tests evaluated the perception of simple shapes, patterns and directional instructions. The results showed that some information is discriminable and that tactile-foot stimulation could be used for a wide number of applications in human-machine interaction. Furthermore, the results also suggested that the blind perform better in some key tasks and support the feasibility of footwear providing tactile feedback for situational awareness, mobility and the navigation assistance of the blind.

“…Our own work presented the design of an on-shoe vibrotactile display prototype for navigation assistance of the blind [20]. In 2009, the last two works reported more mature results in [21] and [22] respectively, while in 2010 a combined audio-tactile system providing the sensation of walking over granular ground was presented in [23].…”

“…Research projects have focused on aiding navigation and orientation through the use of tactile feedback as described in [6] including tactile feedback delivered to various parts of the body through wearable and mobile devices. Research explored smartphones [27], tactile belts [14,38] and shoes [21] to give simple directional cues, as well as symbolic cues for communicating direction [39] and ambient guidance [9,37]. In terms of haptic research, simple directional signals have been explored for guiding pedestrians [24] and navigation through symbolic haptic means in the form of shape and weight shifting technologies [13].…”

“…In addition, our platform can be used in gait recognition. Vel´azquez [5] proposed to instruct the direction to user by using sensors attached to shoe. User can know the direction they want to go, as 16-point array of actuators have different vibration frequencies.…”
